Answer- 3) 117
Explanation-
Let the total number of females who applied for the exam from Chennai are x.
According to question,

x = 143
Number of males who passed the exam from Chennai = 100/3% of 216 = 72
Number of females who passed the exam = 98 – 72 = 26
Required difference = 143 – 26 = 117

x = 396 + 5 = 401
Number of females who applied for the exam from Kolkata = 401 – 225 = 176
Required difference = 176 – 9 = 167

(lll) Mike scores 41% marks and his marks were 472 less than the maximum marks and 32 marks more than the passing marks.

Correct

Answer- 3) Either ll or lll
Explanation-
Let the maximum marks be x.
By using statement ll, we have,
11% of x = 88
x = 800
Marks required to pass the exam = 45% of 800 – 64 = 296
By using statement lll, we have,
41% of x + 472 = x
59% of x = 472
x = 800
Marks required to pass the exam = 41% of 800 – 32 = 328 – 32 = 296

Incorrect

Answer- 3) Either ll or lll
Explanation-
Let the maximum marks be x.
By using statement ll, we have,
11% of x = 88
x = 800
Marks required to pass the exam = 45% of 800 – 64 = 296
By using statement lll, we have,
41% of x + 472 = x
59% of x = 472
x = 800
Marks required to pass the exam = 41% of 800 – 32 = 328 – 32 = 296

60/x = 12 (x is the speed of boat in still water)
Therefore, x = 5 km/h
Speed of boat upstream = 12 – 3 = 9 km/h
Similarly, any two statements can be used to get the answer

Incorrect

Answer- 4) l and lll
Explanation-
By using l and lll, we have,
LCM of 15 and 20 = 60 = Total water to be filled
Water filled in tank in one hour without leak = 60/15 = 4
Water filled in one hour with leak = 60/20 = 3
Time taken by leak to empty the tank = 60/(4 – 3) = 60 hours

lll) Average age of husband, wife and their child is 19 years.

Correct

Answer- 4) l and lll
Explanation-

Let the present ages of husband, wife and child are x, y and z. Then,
x + y = 21 × 2 + 10 = 52
x + y + z = 19 × 3 = 57
Therefore, z = 5
